We’ve detected many exoplanets and exoplanetary stems, they orbit stars in other parts of the galaxy. These planets form the same way our planetary did, they coalesce from a protoplanetary disc of gas and dust. Scientists have recently found a useful kind of substance - heavy water in one of these protoplanetary discs, and it’s told us a lot about how water might end up in planetary systems.
